The primary goal of the National Tennis Rating Program (NTRP) is to help all tennis players enjoy the game by providing a method of classifying skill levels for more compatible matches, group lessons, league play, tournaments and other programs.

The National Tennis Rating Program (NTRP) is the official system for determining the levels of competition for USTA League.

NTRP ratings for all players throughout the country are produced by USTA National using a computer program.
